NJ Transit is leading the investigation. An agency spokeswoman, Nancy Snyder, said Clifford was the 11th person to die this year after being struck by a train on NJ Transit tracks. She said that 20 people were killed on NJ Transit tracks through Aug. 15 last year.

Park Ridge police Capt. Joseph Rampolla said the woman was killed behind a Dunkin’ Donuts, between Berthoud Street and the Montvale border in an area where there is no crossing and there should not be any pedestrian traffic.
